Kilowatts (kW) to Kilowatt-Hours (kWh) Conversion Calculator
The energy E in kilowatt-hours is equal to the power P consumed in kilowatts times the time T in hours. For example, let''s convert 25 kW power used over a 4-hour time period to energy in kWh. EkWh = 25 kW × 4 hours. EkWh = 100 kWh. So, 25 kW of power consumed over 4 hours is equal to 100 kWh of energy. Do you want to convert kWh to kW ?
